IPC Code(s): G06F13/16
CPC Code(s): G06F13/1694
Abstract: a peripheral component interconnect express (pcie) system and method achieve reduced power consumption and latency. when the link transitions from an active functional state in which the link has a first configuration of n active lanes to a power-saving state, the number of active lanes is collapsed such that m of the n lanes are maintained in an active power-saving state and p of the n lanes are maintained in an electrically idle state, where m, n and p are positive integers and n>p>m. the reduction in lane width reduces power consumption. bit values specifying the current link configuration can be saved in a control register and read and compared to bit values contained in a link control register before transitioning back to the active functional state. if the bit values match, the active functional state is resumed directly from the recovery state, thereby reducing latency.

Abstract: a package includes a device that includes electrodes disposed on a piezoelectric layer on a first, front side of a first substrate and vertical interconnect accesses (vias) that extend through the substrate to couple the electrodes to a second, back side of the first substrate. the vias may be through-substrate vias (tsvs). employing a first substrate (e.g., silicon) in which vias can be formed, the electrodes on the front side can be coupled to interconnects on the back side to minimize electrical path distances to and from the device for a higher a q factor. also, a capacitor may be formed on a second, back side of the substrate and coupled to an electrode of the device by a via rather than having an electrical path from a first substrate, to an external capacitor on a package substrate. a thermal conductive path is also reduced for improved heat dissipation.

Abstract: methods, systems, and devices for wireless communications are described. a wireless communication device may receive, via a first radio frequency spectrum band, a control message that includes an uplink grant for sending one or more backscattered uplink messages via a second radio frequency spectrum band that is higher than in frequency than the first radio frequency spectrum band and separated from the first radio frequency spectrum band by at least a threshold frequency gap. the wireless communication device may then receive a continuous waveform via the second radio frequency spectrum band, and modulate the continuous waveform with uplink data of the one or more backscattered uplink messages. the wireless device may then send, via the second radio frequency spectrum band, a backscattered signal of the continuous waveform based on modulating the continuous waveform with the uplink data.

Abstract: aspects presented herein may enable a base station to perform demodulation reference signal (dmrs)-based channel sounding for a channel between the base station and a ue, such that the base station may configure a more suitable precoding for coherent ul multiple input multiple output (mimo) transmission(s) of the ue without increasing communication overhead significantly or at all. in one aspect, a base station performs channel sounding for a channel based on a set of physical uplink shared channel (pusch) dmrs received from a ue via the channel. the base station selects a precoding to be used by the ue for a subsequent pusch transmission via the channel based on the channel sounding. the base station transmits, for the ue via a physical downlink control channel (pdcch), a transmit precoder matrix indicator (tpmi) indicating the selected precoding, where the pdcch schedules the subsequent pusch transmission for the ue.

Abstract: in some implementations, a first access point (ap) selects one or more other aps for participation with the first ap in a coordinated access point transmission session. the first ap obtains a transmission opportunity (txop), and transmits a frame indicating scheduling information for uplink (ul) or downlink (dl) transmissions to or from the selected aps, the scheduling information indicating a respective start time for the ul or dl transmissions to or from the selected aps, at least two of the start times being offset from one another by a time period associated with decoding a preamble of a wireless packet. the first ap transmits or receives wireless packets to or from one or more associated stations (stas) at least partially concurrently with the transmission or reception of wireless packets by the selected aps to or from their respective associated stas based on the scheduling information.
